There are a few things noted in this post; visit the post if you want easier navigation to the various screencasts, etc.
Screencasts
I have two old and three new screencasts up. They are all available for download directly from this site as opposed to uploading them elsewhere. Let me know if they don't work for you for any reason.
- Onion screencast (self-referential structures)
- Map and Fold (higher-order functions)
- Using Subversion (quick, could be better)
- Jan 30 Code Walk (a revisit of our code walk from Friday, re: Lab 2)
- Destructuring Lists (pulling apart Scheme lists; relates to XML lab and future interpreter projects)
The last three of those are new.
So far, I've been producing screencasts that I think might be useful. If you have questions that you'd like answerd as a screencast, please let me know. I'm happy to expand on any of those, or focus in on some particular aspect of the screencast if any of them make things less clear.
XML Lab Update
Lastly, I made a small change to the XML lab. In particular, I clarified a statement I made about the length of solution. I claimed my solution was "only 13 lines of code." My clarification points out that my solution would probably not pass a code walk. Yours might be longer, but as a result it will be clearer and better documented. "Longer" here does not mean an order of magnitude.
